Plancheite is a beautiful copper silicate mineral often found in oxidized copper deposits, closely related to shattuckite and chrysocolla. It forms striking fibrous or botryoidal crystals in vivid shades of blue to blue-green, sometimes with silky or chatoyant textures. In folklore, Plancheite is associated with wisdom and truth, believed to help one speak from the heart. Metaphysically, it promotes clarity, calm communication, and emotional balance, connecting the throat and third-eye chakras for deeper spiritual awareness.
